I know everybody is hunting desperately for these very rare fan brackets. Model # Ch00134-co for the awesome Core X9 case. Seems like they are nowhere to be found in the world.
Well, you're in luck!!! A friend of mine just got himself a 3D scanner and printer. The brackets are small enough to fit his own maximum measurements. He's going to make 9 more for me because I'm gonna go overkill on air fans, maybe more in case I go truly off my rocker. They will be made to the specific plastic content that matches the strength of the originals, plus heat rating.
Anyhow, neither of us knows
